説明
Form: Odorless crystals (pure); yellow-brown viscous semisolid at ambient temperatures (technical grade).
Cypermethrin is a pyrethroid insecticide. It was first synthesized in 1974.
Cypermethrin is a synthetic chemical similar to the pyrethrins in pyrethrum extract (which comes from the chrysanthemum plant). Pyrethroids, including cypermethrin were designed to be effective longer than pyrethrins.

使用
Zeta-cypermethrin is used for the control of Lepidoptera, beetles
and aphids in cotton, fruit, vegetables, field crops, ornamentals and
forestry. It is also used in public health.

生物活性
Type II synthetic pyrethroid insecticide; an extremely potent, cell-permeable inhibitor of calcineurin.

接触アレルゲン
Pyrethroids, also called pyrethrinoids, are neurotoxic
synthetic compounds used as insecticides, with irritant
properties. Cypermethrin and fenvalerate have been
reported as causing positive allergic patch tests, but
only fenvalerate was relevant in an agricultural worker.

環境運命予測
Soil. The major soil metabolite was reported to be 3-phenoxybenzoic acid (Hartley and Kidd, 1987).
The typical half-life of cypermethrin in the soil is 30 days, although it can range from two to eight weeks (6, 9). Soil microbes rapidly break down cypermethrin.
Cypermethrin has an extremely low potential to move in the soil. It is unlikely to contaminate groundwater because it binds tightly to soil particles. Cypermethrin is stable in sunlight.
The average half-life of cypermethrin on foliage is 5 days.

代謝経路
In cabbage plants, (1R)-cis- and (1R)-trans-isomers of
cypermethrin undergo epimerization to (1S)-isomers,
cis=trans isomerization, ester bond cleavage,
hydroxylation of the phenoxy group in the alcohol
moiety or the geminal methyl group in the acid moiety,
hydration of the cyano group to an amido group with
subsequent hydrolysis to the carboxylic acid, and the
conjugation of the carboxylic acid, and alcohols with
sugars.

廃棄物の処理
Incineration would be an
effective disposal procedure where permitted. If an efficient incinerator is not available, the product should be mixed
with large amounts of combustible material and contact
with the smoke should be avoided. In accordance with 40
CFR 165, follow recommendations for the disposal of pes-
ticides and pesticide containers.
